Buy the Spray Research Kit online in Australia, with Selank, Semax and DSIP as three ready-made 10 mL research nasal sprays. The Spray Research Kit in Australia brings together three short neuropeptides, Selank, Semax and DSIP, each as a ready-to-use 10 mL solution with 10 mg of peptide at 1 mg per mL. Selank, the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro with formula C33H57N11O9 and CAS 129954-34-3, and Semax, the sequence Met-Glu-His-Phe-Pro-Gly-Pro with formula C37H51N9O10S and CAS 80714-61-0, are both heptapeptides that came out of the Institute of Molecular Genetics in Moscow. DSIP first appeared in sleep research and is a nonapeptide, written Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, with formula C35H48N10O15 and CAS 62568-57-4. The three bottles ship together in one carton from local stock. Every lot is verified by mass spectrometry with purity measured by HPLC, giving you three certificates to read before you check out. The bottles are supplied already in solution, so you can skip the diluent and the calculator. If you think you will want powder later, the single Selank vial is also available. After unpacking, keep the bottles refrigerated at 2 to 8 °C and shielded from light. These are research reagents from our nootropic peptides range, sold to customers 18 years or older.

For laboratory research use only. Not for human or veterinary use. Not TGA approved. See the NovaPep research use policy.

What Is the Spray Research Kit?

Packed in one carton are three short peptides active in the brain, Semax, Selank and DSIP, each pre-dissolved and sealed at equal strength in its own pump spray bottle. In effect you get three stock solutions of identical concentration, ideal for labs that want a direct comparison of the three compounds without making each one up from powder. You can order the Spray Research Kit online in Australia as three ready-made 10 mL nasal sprays, and every lot ships with its own certificate. Labs planning similar studies can order the Spray Research Kit online in Australia, with identity and purity confirmed on every lot.

The Reason These Three Peptides Are Packed Together

Each is a small, water-soluble neuropeptide researched for effects measured in brain tissue, including behaviour, sleep EEG, neurotrophin levels and gene expression. Two are closely related. Semax, a heptapeptide derived from ACTH, and Selank, which is based on the tuftsin immune fragment, were developed in the same Moscow programme. They share an identical tail of three residues, meaning the only difference lies at the start of the chain. The third, DSIP, the nine-residue sleep peptide, shares neither sequence nor origin with them. That makes it a valuable outsider, because if all three bottles shift a readout in the same direction, the effect is less likely to be something peculiar to the Pro-Gly-Pro family.

Key Facts About the Spray Research Kit

Three bottles, a single compound in each, carrying 10 mg of peptide per 10 mL
The same 1 mg per mL concentration in all three, set at manufacture
Its own lot code and certificate on every bottle
Supplied as solution, so stored in the fridge rather than the freezer

How the Three Kit Peptides Differ in Structure and Action

The Institute of Molecular Genetics in Moscow developed both Selank and Semax, and each finishes with a Pro-Gly-Pro tail that stabilises it. As a tuftsin analogue, Selank is researched in rodent models of anxiety-like behaviour, immune markers and GABA-A receptor binding. Semax, for its part, is the ACTH 4 to 7 fragment lengthened by Pro-Gly-Pro and is researched for BDNF and TrkB signalling in rat hippocampus and in experimental ischaemia.

Both heptapeptides carry the C-terminal Pro-Gly-Pro motif, which slows enzymatic degradation. Selank contains the tuftsin core Thr-Lys-Pro-Arg, while Semax contains the Met-Glu-His-Phe sequence taken from ACTH. DSIP, by contrast, is a linear nonapeptide whose N-terminal tryptophan makes it light sensitive.

Spray Kit Research: What Studies Have Looked At

Delivery by spray mirrors the way much of this research was carried out. In rodents, intranasal delivery is investigated as a way for peptides to reach the brain via olfactory and trigeminal nerve pathways, partly getting around the blood-brain barrier that stops most peptides coming from the bloodstream. Important Semax and Selank rodent studies, among them studies of BDNF in the hippocampus and GABA-related genes in the cortex, relied on the intranasal route. Each compound's own product page covers its research background in more depth.

DSIP comes from a different line of work. It was isolated in 1977 from cerebral venous blood taken from rabbits kept in induced sleep, and has since been examined in animal models of sleep and stress. Combining all three lets a lab test how a sleep-linked nonapeptide compares with two short regulatory peptides within one model while the vehicle and strength stay constant. None of the three is a medicine. They are all research reagents.

Three Very Different Histories

The histories of the three compounds differ widely. Semax is a prescription medicine in Russia and was placed on the Russian essential drugs list in 2011, and Selank is sold as an anxiolytic in Russian pharmacies. Both were developed at the Russian Academy of Sciences' Institute of Molecular Genetics. DSIP took no such route and is still a research peptide, tracing back to a 1977 rabbit EEG study carried out in Basel.

This carton suits projects that set all three neuropeptides against each other at the same concentration. The strength is fixed during manufacture and printed on every label, so your comparison begins on an even footing without three separate reconstitutions.

The kit is delivered in a white and teal NovaPep carton printed with the names of the three compounds. Inside are three pump bottles of 10 mL, holding Selank, Semax and DSIP respectively, with 10 mg of peptide at 1 mg per mL in every bottle and a separate lot number on each label. You do not have to mix anything, which is exactly the appeal of a peptide nasal spray kit, though the trade-off is that the bottles are perishable and not something to leave in a freezer for a year.

Because every bottle comes from an individually tested lot, you have three reports to review. Compare each measured mass with 751.9, 813.9 or 848.8 g/mol, and look up the HPLC purity of every lot in the COA library by the number on its label. Our guide to reading a certificate of analysis explains what every figure means.

Handling and Storage of the Spray Bottles

Peptides in solution cannot be kept in a freezer for months like dry powder. Once you open the carton, keep the bottles refrigerated at 2 to 8 °C, shield them from light and finish them before the label dates. If your project is several months away from starting, buy lyophilised vials and store them at -20 °C instead. Order the Spray Research Kit online in Australia and it travels by tracked Australia Post from our local stock.

Before starting any animal or bench work, we suggest calibrating the pumps. Pump actuators release an approximately constant volume per press, but the precise amount differs from pump to pump and shifts over the first few presses as the dip tube fills. After priming, use an analytical balance to weigh ten actuations per bottle, divide the total by ten and record the volume per press for each lot. Because all three peptides sit at the same 1 mg per mL, that figure turns an equal concentration into an equal amount delivered.

No reconstitution is required. If your lab moves to powder later, here is a worked example for matching the bottles. Adding 10 mL of bacteriostatic water to a 10 mg Selank vial gives a matching 1 mg per mL. For any other combination, use the peptide calculator.

The Spray Kit Compared With Lyophilised Vials

Go with the carton when your design calls for all three compounds as matched, ready-made solutions and you plan to start soon. Go with lyophilised vials when you need another strength or vehicle, want to keep stock frozen for months, or need just one compound, bearing in mind that vials require bacteriostatic water for reconstitution.

Labs expanding their neuropeptide research frequently include Pinealon, a brief bioregulator peptide also in this range. More combined cartons, starter kits among them, are listed in kits and bundles.

Other Names for the Kit Peptides

In the literature Selank is called a synthetic tuftsin analogue or written in sequence shorthand as TKPRPGP. Semax is described as an ACTH(4-10) analogue or abbreviated to MEHFPGP. DSIP is short for delta sleep-inducing peptide, which reads WAGGDASGE in one-letter code.

The carton may also be referred to as a Selank, Semax and DSIP spray set or a nasal spray peptide kit. Whatever it is called, the contents do not change, three bottles of 10 mL, each at 1 mg per mL.

Buy the Spray Research Kit Online in Australia

There is just one configuration. Each single Selank, Semax or DSIP nasal spray is also sold on its own, and the kit costs less than buying all three separately. Should your study require only two of the three, two individual sprays are cheaper than the carton. The kit is the best value when every compound is part of the design from day one, sharing a vehicle and an identical strength of 1 mg per mL, and arriving in a single parcel.

For designs running over several weeks, order multiple kits together and we pack each compound from a single lot under one certificate wherever stock permits. Labs that would rather work with powder can buy Selank and Semax as lyophilised 10 mg vials. Every order is open only to buyers who are 18 or older.

No pharmacy stocks these peptides, since none is registered in Australia. NovaPep operates online only, without a pickup point, and ships the carton to every state and territory from Australian stock. Any kit paid for before 3pm on a business day leaves the same day, as described on the delivery information page.

Where the Selank, Semax and DSIP Spray Kit Stands in Australia

As of October 2026 the Poisons Standard does not name any of the three peptides. We checked the October 2026 instrument for each and found no entry, so none of them has a schedule. That does not turn them into medicines. Any one of them would need to be included on the Australian Register of Therapeutic Goods before it could be supplied for a therapeutic purpose, and approvals granted in Russia do not carry over. NovaPep sells the Spray Research Kit in Australia as research reagents, kept in local stock and intended for laboratory use, available to adults 18 and over and not intended for human or veterinary use. If you only need one compound, start with the single Semax spray or vial, and our research use policy sets out what applies to every sale.

Spray Research Kit FAQ

What is in the Spray Research Kit and how do the peptides differ?

The kit holds three 10 mL bottles of Selank, Semax and DSIP, each at 1 mg per mL. Selank is built on the tuftsin core and Semax on an ACTH fragment, and both end in a stabilising Pro-Gly-Pro tail. DSIP is an unrelated nine-residue peptide first isolated in sleep research.

How is the spray kit used in laboratory research?

It provides three matched solutions for comparing Selank, Semax and DSIP side by side in animal and cell models, with the concentration and vehicle held constant. NovaPep supplies it as research material to buyers aged 18 and over. These bottles are not medicines, and they must not be used in humans or animals.

What is the correct way to store the nasal spray bottles?

Once the carton is open, move them into a fridge at 2 to 8 °C, shield them from light and finish each before its label date. Unlike dry powder, solutions cannot be stored frozen for months, so choose lyophilised vials if your project will not begin for a while.

Is the spray kit or single sprays the better buy?

The kit is better value when you need all three compounds, as it costs less than three single sprays. If you only need two, buying two single bottles is cheaper. Lyophilised vials suit long-term storage or custom strengths better than either option.

Is a certificate of analysis included with the spray kit?

Yes, every one of the three bottles has an individual lot certificate. Identity of Selank, Semax and DSIP is confirmed by mass spectrometry, while HPLC measures purity. View the reports in the COA library using the lot number on each bottle's label.

What is the process to purchase a Spray Research Kit from Australia online?

Place the kit in your cart on this page and complete checkout. It is sent from stock in Australia, and kits paid for before 3pm on a business day ship that same day. All three bottles come ready in solution, so you do not need bacteriostatic water or syringes with this order.
